Diode Resistor Circuits

Help with a Diode Circuit?

Find Vout for the following circuit when Vin = 12V and when Vin= -12V. http://imgur.com/MLLmd.jpg . To me, it seems like in both cases, the circuit would act as a voltage divider with Vout = (Equivalent Resistance of Grounded Resistors)*Vin / Req but with the negative voltage, I think that the node with the diode is an open circuit so its only Vout = 100 ohms*-12V / 100 ohms. The potential difference across the diode is to be taken at 0.6V but I can't see how that would matter. I just see the diode blocking any current through R2 if the voltage is negative. Am I oversimplifying the problem?

Yes, for the negative case Vin = -12 V it is a simple voltage divider giving Vout = -6 V

But for the positive case where the diode is in the forward mode, things get a bit more involved. You solve your circuit in two steps:

a) the circuit without the diode and the associated resistor R2. This would give a voltage of +6 V with a source resistance of 50 Ohms (R1 parallel R2)

b) as a second step you add the resistor R2 connected to a fixed +0.6 V point. The equivalent circuit has a resistor of 50 Ohms connected to +6 V and a 100 Ohm resistor connected to +0.6 V
This voltage divider of the equivalent circuit is having a current of
5.4 V / 150 Ohms = 36 mA
Voltage across R2 is 36 mA * 100 Ohms = 3.6 V
Vout = 3.6 V + 0.6 V = +4.2 V

PullUp Resistor $105.14 High Quality Content by WIKIPEDIA articles Pullup resistors are used in electronic logic circuits to ensure that inputs to logic systems settle at expected logic levels if external devices are disconnected or highimpedance. They may also be used at the interface between two different types of logic devices, possibly operating at different power supply voltages. A pullup resistor weakly pulls the voltage of the wire it is connected to towards its voltage source level when the other components on the line are inactive. When all other connections on the line are inactive, they are highimpedance and act like they are disconnected. Since the other components act as though they are disconnected, the circuit acts as though it is disconnected, and the pullup resistor brings the wire up to the high logic level. When another component on the line goes active, it will override the high logic level set by the pullup resistor. Author: Surhone, Lambert M./ Tennoe, Mariam T./ Henssonow, Susan F.

Arithmetic Circuits $166.02 Algebraic complexity theory studies the inherent difficulty of algebraic problems by quantifying the minimal amount of resources required to solve them. The most fundamental questions in algebraic complexity are related to the complexity of arithmetic circuits: providing efficient algorithms for algebraic problems, proving lower bounds on the size and depth of arithmetic circuits, giving efficient deterministic algorithms for polynomial identity testing, and finding efficient reconstruction algorithms for polynomials computed by arithmetic circuits.Arithmetic Circuits: A Survey of Recent Results and Open Questions surveys the field of arithmetic circuit complexity. It covers the main results and techniques in the area, with an emphasis on works from the last two decades. In particular, it discusses the classical structural results including VP = VNC2 and the recent developments highlighting the importance of depth4 circuits, the classical lower bounds of Strassen and BaurStrassen and the recent lower bounds for multilinear circuits and formulas, the advances made in the area of deterministically checking polynomial identities, and the results regarding reconstruction of arithmetic circuits. It also presents many open questions that may be considered as natural next steps given the current state of knowledge.

Electronic Component $101.96 An electronic component is a basic electronic element usually packaged in a discrete form with two or more connecting leads or metallic pads. Components are intended to be connected together, usually by soldering to a printed circuit board, to create an electronic circuit with a particular function (for example an amplifier, radio receiver, or oscillator). Components may be packaged singly (resistor, capacitor, transistor, diode etc.) or in more or less complex groups as integrated circuits (operational amplifier, resistor array, logic gate etc.) Author: Miller, Frederic P./ Vandome, Agnes F./ McBrewster, John Binding Type: Paperback Number of Pages: 158 Publication Date: 2010/08/03 Language: English Dimensions: 6.00 x 9.02 x 0.37 inches

Pull Up and Pull Down Resistors

Could someone help me understand the solid state tesla coil?

I need to know about the circuits. I know how the basic SGTC works, and I know what the Circuits purpose is, I just need to know what roles the transistors, capacitors, resistors, diodes, MOSFETs, and all that junk play, and how they work together. Im just wanting to know how the circuits work because im building one, and it would be much easier to make if i understood how it worked.

Normally you would hook up a neon sign transformer to the input of the TC. This gives you 2 things you need:
1. a source of ALTERNATING current
2. at a high enough voltage to use in the TC.

The solid state portion (and the ignition coil or flyback transformer you use) has to do the same thing.
1. oscillate to form alternating current
2. provide a high enough voltage for the TC.

Usually one would use an oscillator integrated circuit (555) to start things off, but you can just as easily build an sqaure-wave oscillator using two transistors, two capacitors, and some resistors. The resistors 'bias' the transistors, making sure they are operating at the correct voltages and currents.

The oscillator output is fed to a MOSFET. That transistor acts as a switch to for the current into the primary of the ignition coil (or flyback transformer). In order to generate high voltage out of the coil, you have to interrupt the current on a regular basis (like 500 times per second). The oscillator causes the MOSFET to turn on and off at the frequency it is set to. The current through the MOSFET is in series with the primary of the ignition coil, and by action of the transformer a high voltage is produced at the output.

This high voltage is fed into the TC.
